Ka24e no idle (fresh engine)

Hoping someone will be able to help me out. I just refreshed my ka24e and put it in a new chassis, now that itís all in and hooked up it starts right up by instantly drops idle till it dies. The only way to keep it running is unplugging the maf.

So far Iíve checked while itís running for vaccine leaks and the idle doesnít jump.

Is this a timing problem or am I going to have to bite the bullet and buy a new maf.

I have a video of it running with maf unplugged but Iím not sure how to post it and I also donít have this hooked up due to not having a clue where it goes

*Edit* the engine also had new clutch header egr and emissions delete and inked intake as well all done with the engine I have fpr hooked to manifold, and Iacc and air regulator hooked to pipe leading to intake also brake booster is hooked to manifold and valve cover is hooked to intake. I think this layout is correct?

Sorry never got the pictures but I threw on a new tps I had lying around and unplugged the maf and it idles perfectly at 800, revs to limp and falls correctly so Iím gonna look for a replacement maf I guess, do you know of any that are good and not upwards of 300 dollars?
